My surgeon implanted a DIXI Microdeep D08-15CM SEEG electrode. As you can see in the attached image, this electrode has non-uniform contact spacing, with 3 groups of 5 contacts, with within-group spacing of 1.5 mm, and between-group spacing of 11 mm.
It doesn't look like Brainstorm supports this. In order to allow the user to define an electrode with this pattern, the interface for adding electrode definitions would need optional fields to define the size of "secondary" spacers and where they should be placed.
Is this possible? Thanks!
Hey @aarongeller
Thanks for sharing these models.
Indeed the current version of the GUI assumes a uniform spacing and does not include these models.
We will change the GUI to integrate these non-uniform models, which may take some time.
We are also working to integrate more models in future releases.

Checking in on this solution- we also routinely use Dixi electrodes with nonuniform spacing. I don't see anything to address this in the current release of Brainstorm - but I may be missing it of course. Thank you

@benbrinkmann thank you for reaching out.
Brainstorm currently does not support modelling of non-uniform spaced electrodes. We have it on our to-do list for future development.
